Flash via Q-Flash in BIOS, use "Intact" mode.

I fixed my PC with flash programmer + SOIC8 test clip with cable, thx!

Hi,dsanke
just wondering if asus Z370-i supports 32Gx2 ram.
would you please look into it and do the modding for me? thanks

@Qz Xegony
Every LGA1151 motherboard can support 64G RAM without BIOS modification.
Just do not use some 4Rank double size memory.

thank you

hey, dsanke, it works, thank you so much

@dsanke - is ME FW version 11.8.65.3606 OK to do this with, or need older one?

#38 RE: Make Z370 compatible with 128GB RAM by dsanke 09.12.2019 14:45

@Lost_N_BIOS No ME FW version requirement, but must set HAP bit.

Can't get hackintosh to work afterwards, what exactly did you change @dsanke?????

#40 RE: Make Z370 compatible with 128GB RAM by rootuser123 02.01.2020 12:28

@dsanke The instructions are kind of vague, I’m having trouble on how you found the offsets to hex edit, I understood step 1 but not the rest and also did how you set HAP bit?

@bios_guy May Mac OS need Intel ME not been disabled. But ME on 22nm PCH now won't let us use 128G RAM.

@rootuser123 Use UEFITool to search that hex pattern , and it will report you the offset. And about the HAP bit , at offset 0x102h of SPI dump , put this value into calculator and do "or" with 0x1 ,then write this value back to 0x102h.

#43 X99 using 32GB DDR4 memory modules and 256GB max memory support BIOS mod assistance by XPLives 07.02.2021 19:39

@dsanke, @Lost_N_BIOS

I'm borrowing a X99 Motherboard to do some testing so I'm hoping to be able to test some modified BIOS ROMs to see if I can access 32GB DDR4 memory per memory slot. I won't have this motherboard for too long so if it can be done asap before I have to return it soon possibly in a few days and a week max.

Has anyone ever attempted to modify an X99 BIOS to support 32GB DDR4 memory modules?

The motherboard can support 128GB in total with 8 slots but when booting the motherboard I get Asrock Debug Error Code 55 which means it is a memory issue.

I only need BIOS v3.10 modified as v3.40 removes all underclocking options for my CPU so I prefer v3.10 only. No need to add any CPU Microcodes as it contains everything.

BIOS ROM file for modification:
https://download.asrock.com/BIOS/2011/X9...er(3.10)ROM.zip

I would like to minimize the amount of changes required to just read 32GB DDR4 memory modules. So trying to keep the ME and anything else untouched if that's possible.


UEFI Tool search I found these matching:
Hex pattern "C786....000000....00" found as "C786B000000000040000" in Compressed section/PE32 image section at header-offset E99Dh

Can dsanke, Lost_N_BIOS figure how to modify the BIOS for testing and upload it?

2nd step if this works is seeing if there is an inherent 128GB maximum ram limit and if so can this be changed to 256GB?

If this works somehow that would challenge a Z170-Z370 maximum memory capacity.

Thanks in advance.

Hallo gentlemen! Greeting from Prague, Czech Republic!

Well, I recently bought an ASUS Maximus IX Apex. Its Z270 chipset board with only 2 RAM slots and as usual, officially "limited" by 16GB module per slot. And since I'd like to have 64GB of RAM, but don't want to risk that it would not work with 32GB modules, I would like to edit the bios to "enable" the 32GB modules. I already am familiar with UEFI tool and HxD Editor. According to well precisely written guides here on win-raid I successfully edited couple of antient P45, P43, P31 boards to run old 4-core Xeon processors. Man, I had so much fun those times!

But here, I am not sure and I don't want to mess up the board. Though it has 2 bios chips and the recovery would probably not be a problem, I would rather do exact and precise job and evade any disaster recovery, you know?? And I also don't want to buy a quite expensive set of RAM that couldn't use then.
So, I have couple of questions!

1. Since the board will probably not have the latest bios flashed, shall I first flash the latest bios? Then dump it, edit it and flash again?
2. Or should I just download the latest bios .CAP file, edit it and ten flash it as a normal bios update?

3. I downloaded and opened the .CAP file in UEFI tool, searched for the GUID mentioned in the first post on the first page {A8499E65-A6F6-48B0-96DB-45C266030D83} and extracted with "Extract as is" the SiInitPreMem block as a BIN file from there - 380kB. Then I opened the SiInitPreMem.BIN in UEFI tool separately and searched for the "C786....000000....00" with these multiple results:
Hex pattern "C786....000000....00" found as "C7860C54000000000000" in /UEFI image at header-offset 1197h
Hex pattern "C786....000000....00" found as "C7868403000000000000" in /UEFI image at header-offset 7573h
Hex pattern "C786....000000....00" found as "C7866725000000200000" in /UEFI image at header-offset 1E2AEh
Hex pattern "C786....000000....00" found as "C7866725000000800000" in /UEFI image at header-offset 1E2BAh

Now I don't know which one to edit and what to put in. Can you please, advise? Or does the last pattern mean that this bios file is ready to work with 32GB RAM modules, so 64GB kit will work?

Thank you, anybody, for any advise!

Chat ya boys, soon!

Regards

Couple hours later....

Hey, I think, you can forget about my questions now... I just discovered the CoffeTime tool v0.92 with a simple and easy GUI that does all the necessary modifications for me with just few clicks! This tool is freakin amazing!!! It modds the .CAP file directly which is cool. And along with the 128GB RAM tweak, I might be also able to use all the top 6th-9th Gen. Core i7 and i9 CPUs, since most of the microcodes fit (from size point of view) and that is AWSOME!!!! So I immediately ordered Core i7-9700KF that only needs a little HW mod on the pins side of the substrate and thats it!! I let know during next week, how this whole HELL OF A HACK ended up... wish me luck!

Cheers!
